In my mind, signature campaign is an easy way to get started and earn some coins, but most campaigns are only open to high ranked users. some campaigns however, do accept newbies, like me. and i have noticed that most of those campaigns are about a new altcoin, and pays in that certain type of altcoin, which requires me to get a wallet of theirs. Any thoughts on whether its a good idea to participate in those campaigns or potential riskes?
first of all you should only join a signature campaign when you are at least a Jr. member and even if they are accepting Newbies you should wait. because the amount of payment is dust and also you don't naturally know anything about anything, what are you going to post comment about then!
also you don't really need to keep altcoin wallets on your computer to accept those altcoins if you can go on an exchange service and use their wallets, you would eventually want to dump that altcoin for bitcoin anyways so it is better to keep it directly there.
